I’m blocked because this session has no remaining execution credits, so I can’t inspect or modify the project yet.
Current project state from the provided context:
- Empty schematic: 0 components, 0 nets.
- Draft placeholder project name/description still unchanged.
- No Ethernet PHY, magnetics/RJ45, MCU/processor, or ADAU DSP has been selected or wired.
What remains to design:
- Identify the exact ADAU DSP part number, because most ADAU DSPs do not have a native Ethernet MAC/PHY.
- Choose the Ethernet architecture:
- MCU/SoC with Ethernet MAC/PHY bridging control/audio data to the ADAU over I2C/SPI/I2S/TDM, or
- Ethernet audio module/protocol solution if you need audio-over-Ethernet.
- Add required blocks: Ethernet PHY or module, RJ45 with magnetics, ESD/protection, clocking, power regulators, DSP power/decoupling, programming/control interface, and audio I/O as needed.
- Verify all IC wiring against datasheets, then run schematic review before layout.
Key clarification needed when work resumes: which ADAU chip are you using, and do you want Ethernet for control/configuration only, or for streaming audio over Ethernet?
